INDIVIDUAL GLASS POT OR TANK.

Specification of Letters Patent.

Patented Dec. 1, 1908.

To all whom it may concern:

Be it known that I, Jonn I. AnBooAs'r, a.

citizen of the United States of America, residing at Pittsburg, in thecounty of Allegheny and State of Pennsylvania, have invented certain newand useful Improvements in Individual Glass Pots or. Tanks, of which thefollowing is a specification, reference being had therein to theaccompanying draw- This invention relates to an individual glass pot ortank, and the objects of the invention are, first, to provide a pot ortank wherein a combined stopper and burner are employed for melting thecontents of the pot or tank, second, to dispense with the use of largetanks and furnaces in factories, thereby reducing the cost of fuel andtime heretofore incurred by negligence on the part of workmen, strikes,*and other occurrences detrimental to the production of glass ware;third, to provide a pot or tank for melting the material from whichglass is made which will be simple in construction, durable, and of suchconstruction that it can be easily filled and the material melted. Iattain these objects by a pot designed for small batches ofmateriahalthough the pots can be con,- structed of an excedii'igly largesize.

In providing an individual pot, I not only attain the objects abovespecified, but increase the output of a glass factory, insure a\liigherhgrade of production and facilitate the work in general in theproduction of all ki ids of ware.

he invention will be described in detail and theri specifically pointedout in the appended claims.

In thcdrawing: Figure 1 is a side elevation of a pot constructed inaccordance with my invention, illustrating the pot in a tilted positionfor receiving material automatically from a hopper located above saidpotor tank, Fig. 2 is a longitudinal sectional View of the combinedstopper and burner used in connection with the pot, Fig. 3 is a verticalsectional view of the ot, illustrating the burner in elevation, F 1g. 4is a cross sectional view of the burner, Fig. 5 is a front elevation ofthe pot, Fig. 6 a vertical sectional view of a modified form of pot, andFig. 7 is a plan of the same.

To putmy invention into practice, I provide bearings l,between which istrunnioned the pot proper, consisting of walls 2, a bottom and a top 4.The bottom 3, top 4 and the walls 2 are made of a non fusible mate rialand are connected together by metallic straps 5 or similar fasteningmeans.

One of the side walls 2 at its upper edge is provided with ank opening 6through which material. is placed into the pot, the pot being tilted toallow material to pass from the hopper 7 suitably supported above thepot. This hopper is provided with a gate 8 for automatically controllingthe discharge of material from said hopper into thepot or tank.

In connection with the pot I use a combined stopper and burner of anovel colistruction. The combined stopper and burner are approximatelythe same size as the opening 6 and are adapted to protrude therein. Thestructural features of the stopper and burner are a mushroom head 9having exterior corrugations 10, these corrugations allowing gas andfumes to escape from the pot, while the contents-thereof are beingmelted, also allowing a suflicient quantity of air to enter the'pot, toassist in the combustion Within said pot, and insureproper consistencyof the glass being melted.

The mushroom head 9 has a central opening 12 and is connected to asuitable gas supply pipe 13, preferably of a flexible na ture, wherebythe stopper and burner can be removed when it is desired to tilt themelting pot. The gas supply is under pressure and the intensity of theflame is adapted to melt the material contained within the pot.

In Figs. 6 and 7 of the drawings I have illustrated a modified form ofpot having a neck or spout 14, this neck or spout accommodating astopper and burner, besides being used as an. opening for placingmaterial in the pot and removing the same after it has been melted.

With an individual potsuch as above de scribed, it will be evident thatshould any one of a series of pots, be damaged, it will not place anyother of the series out of commission, and the damaged pot may berepaired without interfering with any of the other pots.

in arranging the pot beneath a suitable hopper containing material fromwhich glass is made, I avoid the necessity of re ing, and a combinedstopper and burner for.

said opening, comprising a hollow head provided with an opening in eachend and having a fiat upper face and curved side walls and bottom walland provided with longitudinally extending corrugations, substantiallyas described;

2. The combination with a glass pot having a combined filling and burneropening, of a combined stopper and burner for said opening comprising ahollow head provided with longitudinally extending exteriorcorrugations, said head provided at each end with an opening.

3. A combined stopper and burner for the opening of a glass pot,comprising a hollow head having a flat upper face and curved side wallsand bottom wall, said head provided with an opening in each end, andhaving longitudinally extending exterior corrugations.

In testimony whereof I. affix my signaturev in thepresence of twowitnesses. 1
